Linux systems have a way of identifying device files via major device numbers, which identify modules serving device files or a group of devices, and minor device numbers, which identify a specific device among a group of devices that a major device number specifies. In the driver code, we can define these numbers as constants or they can be allocated dynamically. In case a number defined.Oct 1, 2011 This article, which is part of the series on Linux device drivers, gets you started with writing your first USB driver in Linux.

Whether a driver for a USB device is there or not on a Linux system, a valid USB device will always be detected at the hardware and kernel spaces of a USB-enabled Linux system, since it is designed (and detected) as per the USB protocol specifications.

Writing a Linux Kernel Driver for an Unknown USB Device The Device Driver. Writing code for the kernel is an art by itself and I will only touch the tip of the iceberg. To get a deeper understanding I recommend the books Linux Device Drivers and Understanding the Linux Kernel. As for many other disciplines the separation of mechanism and policy is a fundamental paradigm a programmer should.The first thing a Linux USB driver needs to do is register itself with the Linux USB subsystem, giving it some information about which devices the driver supports and which functions to call when a device supported by the driver is inserted or removed from the system. All of this information is passed to the USB subsystem in the usb_driver structure. The skeleton driver declares a usb_driver.
